Lay your ruler. Now: which detector is better?

What that answer leaves out

Color does not specify the decision boundary.

Excluded world. An identical population cut at another threshold is left out.

Align the operating point before comparing decisions.

Excluded world. A comparison using a different population or cut is excluded.

A shared ordering still permits different cut points.

Excluded world. The same population with the ruler at the opposite end is left out.

A name does not identify the operating point.

Excluded world. The same named detector used at another threshold is left out.

fixed strict ordering of 20 objects; one ruler; binary suffix readout

overlap between the two detectors; use D-002 for that
These are self-audited digital models, not independently verified physical devices.
No learner efficacy, transfer, accessibility equivalence, or vendor performance has been measured.
Unbounded and temporal devices remain text exercises; no faithful state machine is asserted for them.
The receipt exercise has no supplied totals or ceiling, so it supports no computed denominator here.
The digital model audits one ruler on a fixed strict ordering, not coupled rulers, ties, or detector performance.

Look away from the object, then answer the question again. This is a prompt for reflection, not a measured learning outcome.

What must match before you compare the rulers?
